So, all the other classes are having a merry time speculating about what's on the chopping block for them. I can definitely feel the bloat, given that there's two spells that I actually use and can't even spare a click-slot for: Mind Vision and Renew. (I use them by opening chat and typing /cast ... >.>)
So, what can go? I think a big part of the problem isn't class abilities so much as it's a lot of items and non-ability macros eating half my action bar slots. Things like: on-use trinkets, tailoring nets, Rod of Ambershaping, Symbiosis, G91 Landsharks, three kinds of potion (Int, mana, and Kafa Press), Healthstones, drinks (conjured and otherwise), mounts, and Ra'sha's Sacrificial Dagger. I'm sure that some people don't bother with so many different items, but aside from the Landsharks, I can't really live without them.
One thing I do think should be done is more macro modifiers. You know help/harm macros? It'd be great if I could do something like:
Currently I have all those abilities linked with things like [nomod], [mod:ctrl] and [mod:shift]. If we could get the modifiers for type and immune, that'd allow me to fit more abilities into the same keybind by freeing up the shift+X and ctrl+X spots.
/cast [type:undead] Shackle Undead; [noimmune:root] Embersilk Net; Rod of Ambershaping
Another thing that would free a few slots on my bars: make PW:Fort passive and/or automatic, and make Inner Fire/Inner Will passive, and let the spell switch which one you have. That'd save two more buttons and change almost nothing.
